6 FAQs about [Battery power line resistance]

What is a low internal resistance battery?

One of the urgent requirements of a battery for digital applications is low internal resistance. Measured in milliohms, the internal resistance is the gatekeeper that, to a large extent, determines the runtime. The lower the resistance, the less restriction the battery encounters in delivering the needed power spikes.

What is internal resistance & how does it affect battery performance?

Fact: High internal resistance can lead to significant energy losses in the form of heat. This not only reduces the efficiency of the battery but can also pose safety risks in extreme cases. At its core, internal resistance is a measure of how much a battery opposes the flow of electric current.

What is the internal resistance of a lithium ion battery?

The typical internal resistance of a lithium-ion battery varies depending on its capacity and design. Generally, it ranges from a few milliohms to tens of milliohms. For example, a 2000 mAh lithium-ion battery may have an internal resistance of around 50-100 mΩ. Can high internal resistance cause a battery to fail?

How to measure battery internal resistance?

The pulse load test is another method for measuring battery internal resistance. It involves applying a short-duration, high-current pulse to the battery and measuring the voltage response. The internal resistance can be calculated from the voltage drop during the pulse. 1.

Can high internal resistance lead to battery failure?

Yes, high internal resistance can lead to battery failure. It reduces the battery’s ability to deliver current, causes voltage drops, and generates excessive heat. Over time, high internal resistance can cause permanent damage to the battery, leading to reduced capacity and potential safety issues.

What is the internal resistance of a cell phone battery?

The internal resistance varied widely and measured a low 155 mOhm for nickel-cadmium, a high 778 mOhm for nickel-metal-hydride and a moderate 320 mOhm for lithium-ion. These internal resistance readings are typical of aging batteries with these chemistries. Let's now check how the test batteries perform on a cell phone.
